To @M -whom t may concern.'

Be 1t known that I, FREDERICK A. HART, a citlzenof the United States, residing in Jersey City, in the county of Hudson. and

State of yNew Jersey, have invented certain new and useful Imprm-ements in' Type- Y 1V riting Machines,'of which the following is a specification. j

' This invention relates to Carriage-return devices 'employed incertain classes of ma-j Chines, forV instance in vcombined typewrit- Ing and computing maclnnes4 of the class illustratedin my pending applications No.. '466.836, filed December`10,'1908, and No.

1,596,451, filed Dec.; 9, 1910.

l' According to said first-mentioned application, in` performing the operation of addition upon a -typewriting machine, the numeral keys Vnot, only print upon the work sheet, but also set up certain pins, and after the completion 'of the writing ofa number,

ahandle (designated herein as 16) is pulled wheels.

for' the 'purpose of -'turning certainv dial wheels', each to an extent determined bythe key-set` pin' associated therewith. handle is usedfor. reciprocating a general operator, whichin turn operatessaid dial Anotherffunction performed by said general operator, which may be driven. by a motor aswell as by hand as ,in my` application, No. 596,451, above mentioned, 'isy to return. the carriage of the typewriter. In practice, thel length of run ofthe typewriter carriage varies, whereas the vstroke of the general operator is uniform. Hencel in said applications, there was shown an adjustment device between said general operator and the typewriter carriage, so thatV during part of the advance stroke of the general operator the typewriter carriage could remain stationary, if desired; the general operator `.picking up the carriage at thev proper time, so that the carriage would vloe driven during only the desired portion of the stroke of the' K general operator.

The length of In said applications, 1t was necessaryl not only to adjust the relation between said gen- Said strokel of the typewriter carriage 1s usually determined by means of,

eral operator and the carriage,but alsorto adj ust the aforesaid margin gage, and unless the Operator was particular to efl'ect'both adjustments in the proper manner, difliculty might result, since the carriage might be arrested by its margin gage prior to the completion of the forward stroke of the general Operator; or the adjustmentl between the general operator and the carriage might notg'correspond with the adjustment ofthe margin gage on the typewriter.

Patented Feb. 13, 1917.-

One of the .principal objects of the present l improvements is`to avoid this difficulty and to render the device more simple 1n constructionand operation.

To these and other ends, I connect to themargin gage of *the typewriter a device which also sets the aforesaid adjustment mechanism between the. general operator andthecarriage. It is therefore only necessary forthe operator to adjust the margin gage in the usual manner, whereupon the carriage, during its return strokes, will always stop at the point determined by said margin-gage, and theproper -connection is always made between the aforesaid general .operator and the carriage, so that the general operator imparts vto theA carriage the proper amount o f movement, and there is no danger'of faulty action of any of the parts.

In other words, vthe invention relates largely to an automatic adjustment 'of the vice remote from the 'carriage itself, land the carriage. was returned either manually or@` automatically, concomitantly with the actuation of certain other mechanism; and one of the features of the present invention resides in providing means to adjustthe con-I nection between the carriage and a carriagereturning. device having uniform movement, to, correspond to .the variable movement o'f f the carriage. `T he device for limiting the' return of the carriage is adjusted consentanecarriage to its returning mechansim. v This 105 ou'sly- 'with the device whichy connects the ffeature of the invention may be carried out y in a variety of ways, asv for example, by pro- '.Vidinga stop "or margin gage fory the return movement f the carriage, which is ope-ratively Connected to a device which governs mechanism at another point of adjustment. Fig. 4 is a vertical section takenalong the operator shaft..

Fig.. 5 is an enlarged fragmentary view in' side elevation, with parts broken away to show the under-lying structure, andv showing the control in a position corresponding to the position of the stop, as

illustrated in Fig. 2.

Fig. 6 is a view similar to Fig. 5, showing the control in the position corresponding to the position of the stop, as illustrated in Fig. 3.

Fig. 7 is a horizontal sectional view.

Fig. 8 is. a fragmentary detail perspective view of certain of the coperating stops.

Showing the invention as embodied in an Underwood typewriter, 1 indicates a carf riage which supports the usual platen 2 in the customarymanner. The carriage 1-.is mounted in the usual way to slide back and forth on a frame 3, for the purpose of bringing the work sheet to the different po-l 'Y sitions desired in the actuation of the ma# chine.

It is generally understood that lthe carriage 1 travels from right to left, as viewed in Figs. 2 and 3, in the ordinary operation of the typewriter in lettersspacing.- It has been found desirable to limit the extent .of movement of the carriage in 'both direc-v tions, so as to limit the width of the l'typewriting on the work sheet supported by the platen 2. For this purpose, the carriage 1 is provided with a margin stop or gage 4, which engages at the end of its movement 1n a letter-spacing direction,- a stop `5,

adjustably mounted on the frame 3 in anyv suitable manner, as by beingslidingly supported on bars 6 and 6 and adapted to be secured in anyadjusted position' by a lock 7, which may be in the form of a ratchet pawl, engaging a rack on bar 6.

The return movement of the carriage after the Writing of a line, may be also limited in a similar manner by the carriage stop 4 e ii' 'v gaging a margin stop or-gage 8, A which Simi.-

showingvthe return carriage stop and the connected lar tothe stop y5, is slidingly mounted on bars 6 and. 6 and adapted to bey secured in any adjusted position by means of a lock 9, which is shown in the form of a pawl engaging a rack on the bar 6.

In order that the operative may accurately adjust the limits of throw of the cara position, that the stops 4, 5' and 8 will be convenientlyl located with respect thereto, so that the relative positions4 of the. stops 5 and 8 can be easily read on the scale. In

- order to aid the facility of reading, these stops may be provided with pointers 11, 12

' and 13 which overlap .the scale 10.

l Whilevthe stop 4 lon the carriage may be a. simple projecting lug, it .may also be of the typeshowii in Fig. S which is common to the Uiiderwood typewriters and embodies a ca'm lug 4, which coperates with the v riage, a scale 10 may be provided in such stop 5', and a spring-pressed pivotally.

mountedreleasable lock 4"., which. coperates with a lug 8?' forming part of the stop 8;

As is usual in the Underwood machine, there is piovided a. platen spacer v14 which may be seized by the operative iii the opera-- tion of returning the lcarriage,-and it will sie simultaneously revolve the-platen the desired amount, to bring'a freshy portion of thework sheet in .operative position.

As described in my abovementioned ap;-` plication, the return of the carriageand the operation ofthe platen spacer may be controlled from. a point other than the'carriage itself, as for example by connecting towthe spacer 14, a flexible connection 15 shown-in the form of a ribbon, and adaptediobe operatively. connected. to'. an l"operator, 16 through intermediary mechanism.- -The op erator 16 may be of any suitable type, such as automatic or power-actuated, as lshown in my abovementioned applications, or'. itmay be a manual means, 'as the hand-crank l here shown.

In the embodiment ofthe invention here` with illustrated, the ribbon 15,. passes'. .over

aguiding roller 17 intermediate its" ends, so as to change its direction of pull, and is 'connected at the opposite end'from that at l which it is attached tothe spacer 14,l to ak drum 18. `The vdrum'18 issecured to a' stub- Q shaft 19, on which is also secured `a'pinion- 20 meshing with a 'gearl 2 1loosely mounted -on a shaft 22.` Inthis case, the .operator 16 is shown as' being loosely .mounted onthej shaft' 22., and connected toa-i1 arm 23,- as'by' means of a pin 24, so'as to 'move with the arm 23, and also with the shaft 22 to .which the arm 23. is fxedly secured.

The arm 23 is provided with fa pinion 25 which meshes" with-the gear-21 in `such a manner,that the ai-m'` 23 and thus the operator 16, are free to rotate 'relativeto the gear 21 luntil thel .pinion`25 :meshes with a corresponding pinion -26`alo meshing. with ed relative to the shaft the gear 21, and carried by a control 27, shown in the form of an arm loosely mount-v 22, as by .being journaled on the lhub extensions ofthe gear 21.

It will be seen that when the gear 25 meshes with the gear 2, the' operator 16 will be locked to the gear 21, whereby this mechanism` forms a clutch connecting the operator to the gear 21, so that the former will be capable of driving thelatter.

It is to be noted that the initial position of the control 27 governs the amount of ineffective or inactive movement of the operator 16 before the pinion 25 locks with the pinion 26 to form a driving connection between the operator and the gear 21. It is desirable to effect the positioning of the control 2T .from an accessible point, and also as stated above, in connection with the adjustlnent 'ot' the limit stop for the return of the carriage. 1

v In the embodiment of the invention shown herewith, the. control 27 has operatively con'- nccted thereto in a suitable manner, as for example, by .being rigidly secured. thereto,

an actuator 28, shown in the form of a bell` .crank lever having a segment rack 29 formed on one arm thereof, which meshes4 with a pinion 30 secured in driving relation with a drum 31.

,The drum 31 provides means on Which a flexible connection 32, 'shown in the form of a band, can be Wound, and this flexible connection extends through 'suitablej guiding means shown in this case inthe form of an opening 33 in thev frame 3, to a point'vvhere it is suitably secured to the carriage return stop 8. While the movement of the stop 8 to the left Vwill actuate the control injone direction, it is desirable tolactuate it in the opposite direction, and for this purpose the other' arm ofthe actuator orbell-crank lever 28 is connected to a 'spring 34, which is' fixedly secured at its opposite end.

It Will thus be-seen that 'as the stop 8 is i adjusted and locked in its adjusted position 4to vary the return limit o f the carriage 1, the

flexible connection 32 will be taken up or let out a corresponding amount whiclrvvill be allowed for bythe turning of the-drum 31 under therestrainingcontrol of the spring 34. This will vary the position of the control27 relative to the initial position of the arm 23, and thus the operator 16, so that the latter will have a variable ineffective travel which will allow for the .diiference in its definite fixed traveLand the variable throw of the carriage 1. For example, if the stop Sbe moved'from the position shown in Figg'2 to the position shown in Fig. 3, the return movement of the carriage .Will be limited to the position whichthe carriage occupies in Fig.l 3, where as before, it was limited to the position occupied in Eig. 2. Inasmuch as the stop 8 limits the return of claim: j

' Y 1. The combination with `a typewriter car- .Y

the carriage by engagement with the stop l on the carri age, the operating return mech-v anism for the carriage must be correspondingly limited. This is done as will'evidently bessen, by the flexible connection 32 unwinding on the drum 31, thus swiinging the control arm 2T from the positnonoccu;L pied in `Fig. 5 to the position occupied in Fig. 6, whereby the arm 23 and thusthe -operator .16, will'have a greater inactive orma;v

ineffective 'throw before the pinions 25 and 26 mesh to lock the operator in driving-te.- lation with the gear 21. j

Since ythe operator 16 isV locked to the gear 21, it will rotate the drum 18 through the intermediary of the gear 20, and thus wind up on the flexible connection "15, andl return the carriage 1, at the same time actuating the spacer 14 and spacing the platen, during the remainder of the movement of .the operator.

Theoperator itself may bev returned to its initial position through any suitable mechanism connected or notto the shaft 22, such as that' indica-ted in'my above-1nentioned applications, it beingreadily seen that-the pinion 25 will .disengage itself from the pinion 26,# and travel to the right without disturbing the position of the gear 21, and thus without disturbing the position of the carriage; that is to say, the upper end can have a-"free or ineffective return motion for l its entire stroke or swing.

As the carriage itself movestovvard the left in Figs.`2 and 3,` under the actuation of the usual letter-spacing or columnfspacing mechanism, the flexible connection 15 will gradually unwind from the drum 13 roerator would be depended upon -to determine the limit of return movement of the car- *tating the same, and thus returning the gear i I21v and the control 27 to their initial position` reached at 'the arrival of the carriage 1 at riage.A Itis, however, preferred to use the member 8 as a stop, as Well as an indicator,

inasmuch as thelimit of 'movement of the carriage would probably be more' accurately determined. l f

Variations may 'be resorted to within the scope of the invention, a'nd portions of the improvements may be used without others.
